Abstract
The utility model relates to a door lock device for switch cabinet, in particular to a new type hypopiesia catenation door lock device, which comprises an electromagnetic lock provided on the door panel. The utility model is characterized in that the return circuit power supply of the electromagnetic lock is in series with the normally closed assist contact of a breaker, by which the device mainly solves the technical matters of no catenation between the fixed cell gate panel and the breaker inside in current products. The utility model is easy to unlock and protects the operators.
Description
Technical field:
The utility model relates to the door lock assembly of switch cubicle, particularly a kind of novel low-tension switch cabinet door interlock.
Background technology:
At present, the low-tension switch cabinet that each manufacturer of complete electric utility makes, no chain between its fixed cell door-plate and the interior dress circuit breaker, everybody, and the door lock that adopts locks the door of fixed cell, and it is universal that key is generally.
As: Chinese utility model patent specification (Granted publication number: CN2401673Y) disclose a kind of switch cubicle door lock, this switch includes lock body and installing hole thereof, lock springboard and the spring torsion spring thereof hinged with lock body, it is characterized in that locking the springboard other end be arranged on the lock body and after be equipped with stage clip sliding push pedal take on the rank inserting, be provided with the thrust lock core in the sliding push pedal mesopore, promote sliding push pedal and just easily open the lock springboard, sliding push pedal pore location is provided with the thrust lock core and plays the people and be the lock control effect.
For another example, Chinese utility model patent specification (Granted publication number: CN2571951Y) disclose a kind of door lock that is used for switch cubicle.It comprises housing, inner housing, drive bolt, handle, hyoplastron and lock, lock core, dead bolt, snap close, and its feature is: design a step with the junction of handle on inner housing, dead bolt stretches out from the inner housing step, and snap close is arranged on the handle.It can prevent effectively that instrument from directly contacting dead bolt from handle and inner housing seam crossing, has the good advantage of pick-proof performance.
As mentioned above, when professional electrical maintenance personnel operate low-tension switch cabinet, so often there is drawback: since no chain, opening door operation may be caused, can not guarantee personal safety.
The utility model content:
The purpose of this utility model provides a kind of novel low-tension switch cabinet door interlock, and no chain technical problem between the fixed cell door-plate of solution existing product and the interior dress circuit breaker can the handled easily person be unblanked, and can ensure operator's personal safety again.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of novel low-tension switch cabinet door interlock comprises the electromagnetic lock that is arranged on the door-plate, it is characterized in that: the normally closed auxiliary contact of the electric power loop string circuit breaker of electromagnetic lock on this door-plate.
Described novel low-tension switch cabinet door interlock is characterized in that: the normally closed auxiliary contact of electric power loop string circuit breaker after a plurality of electromagnetic lock parallel connections.
Described novel low-tension switch cabinet door interlock, it is characterized in that: a plurality of electromagnetic locks are installed in respectively on a plurality of unit door-plate.
Described novel low-tension switch cabinet door interlock, it is characterized in that: this electromagnetic lock also has the key hole of manual unlocking function.
By said structure, the utlity model has following technique effect:
1, uses the utility model device safe and reliable, guaranteed personal safety.
2, use the utility model device to save cost, about 150 yuan in an about cover, the competitive strength of raising product.
3, the utility model device highly versatile is applicable to various cabinet type circuit breaker fixed cells, and convenient and simple.
Description of drawings:
Fig. 1 is the structural representation of the utility model low-tension switch cabinet.

Among Fig. 1,2:
The 1-upper sealing plate;
2-instrument door;
3-breaker unit door;
The 4-circuit breaker;
The 5-electromagnetic lock;
Shrouding under the 6-;
51-circuit breaker auxiliary contact;
61-electromagnetic lock power line.
Embodiment:
See also Fig. 1,2, they are structural representations of a kind of novel low-tension switch cabinet door interlock of the utility model.As shown in the figure: it comprises the electromagnetic lock 5 that is arranged on the door-plate, the normally closed auxiliary contact 51 of the electric power loop 61 string circuit breakers of electromagnetic lock 5 on this door-plate.Electromagnetic lock on the utility model employing unit door-plate and the auxiliary contact of this unit breaker are used the requirement that reaches chain: the normally closed auxiliary contact of electromagnetic lock electric power loop string circuit breaker, when circuit breaker is in "on" position, the outage of electromagnetic lock electric power loop, lock can not be opened; When circuit breaker is in gate-dividing state, the electromagnetic lock electric power loop is connected, and lock can be opened; If system blackout is then opened door by the key release and is overhauled.
The utility model can also adopt following version:
The normally closed auxiliary contact of electric power loop string circuit breaker after a plurality of electromagnetic lock parallel connections, a plurality of electromagnetic locks are installed in respectively on a plurality of unit door-plate.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present utility model.
